Problems solved by technology

[0003] At present, ultraviolet curing vacuum coating coatings cannot be sprayed electrostatically. The reason is that it is difficult for coatings to meet the requirements of vacuum coating and electrostatic spraying at the same time. Nowadays, air spraying and other methods are mainly used for construction. The phenomenon of coating overspray is serious, the consumption of paint is large, and the utilization rate of coatings is high. Low, harsh working environment, serious pollution, and poor quality of spraying on the edge of the product, resulting in low production efficiency, low yield rate, increased cost, and reduced profit, hindering the development of the UV-curable vacuum coating coating industry

Description

technical field [0001] The invention belongs to the technical field of ultraviolet light curing coatings, in particular, the invention relates to an ultraviolet light curing vacuum coating metal primer which can be electrostatically sprayed. Background technique [0002] Vacuum coating technology is a new technology developed in the past ten years. It can coat a thin metal layer on the surface of the plated parts to give the base material a metallic luster. In the process of vacuum coating, the vacuum coating primer must be coated on the surface of the substrate first, otherwise the coated metal film is easy to fall off. Therefore, the quality of the coating depends largely on the quality of the primer. [0003] At present, ultraviolet curing vacuum coating coatings cannot be sprayed electrostatically. The reason is that it is difficult for coatings to meet the requirements of vacuum coating and electrostatic spraying at the same time. Nowadays, air spraying and other method...
